问如何解决从角5到java REST服务调用的POST请求错误问题？

EN

我尝试使用restful服务从angular 5应用程序向java应用程序提交POST请求时，从tomcat上运行的java应用程序收到以下错误：

java：445）org.apache.coyote.http11.AbstractHttp11Processor.process（AbstractHttp11Processor.java:1115）atg.apache.coyote.AbstractProtocol $ AbstractConnectionHandler.process（AbstractProtocol.java:637）at org.apache.tomcat.util .net.JIoEndpoint $ SocketProcessor.run（JIoEndpoint.java:318）at java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1145）at java.util.concurrent.ThreadPoolExecutor $ Worker.run（ThreadPoolExecutor.java:615 ）atg.apache.tomcat.util.threads.TaskThread $ WrappingRunnable.run（TaskThread.java:61）at java.lang.Thread.run（Thread.java:745）引起：java.lang.AbstractMethodError：javax。 ws.rs.core.Response.getStatusInfo（）Ljavax / WS / RS /核心/响应$ StatusType; 在javax.ws.rs的javax.ws.rs.WebApplicationException.computeExceptionMessage（WebApplicationException.java:211）。53）atg.jboss.seam.resteasy.ResteasyResourceAdapter.getResource（ResteasyResourceAdapter.java:121）at org.jboss.seam.servlet.SeamResourceServlet.service(SeamResourceServlet.java:80）at javax.servlet.http.HttpServlet.service （HttpServlet.java:731）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:303）... 44多个2018年9月26日下午11点26分22秒org.apache.catalina.core.StandardWrapperValve在路径[/ jboss-seam-jpa]的上下文中调用SEVERE：servlet [Seam Resource Servlet]的Servlet.service（）抛出异常[Servlet执行引发异常]，原因是java.lang.AbstractMethodError：javax.ws.rs .core.Response.getStatusInfo（）Ljavax / WS / RS /核心/响应$ StatusType; 在javax.ws的javax.ws.rs.WebApplicationException.computeExceptionMessage（WebApplicationException.java:211）。

Angular 5应用程序代码：

const httpOptions = {
    headers: new HttpHeaders({ 'Accept': 'application/json', 'Content-Type': 'application/json' })
};
private baseUrl = 'http://localhost:8080/jboss-seam-jpa/seam/resource/rest';

 addLocation(locationTemp: Location): Observable<any> {
    return this.http.post(`${this.baseUrl}/Trips/Location`, JSON.stringify(locationTemp), httpOptions);
}

Java代码：

@POST
@Path("Location")
@Consumes("application/json")
public Response addLocation(Location location) {
        myDao.addLocation(location);
        return Response.ok().entity("Location added successfully").build();
}

java应用程序中的一些jar：

这是web.xml的核心过滤器配置，请注意@GET请求从角应用程序到java应用程序正常工作。
